REVERSIBLE REE Eon STRIP-APPLYING MAoHnvns original application filed m z, 1926,

My inventionrelates to reels, and more particularly to apparatus for supportlng a web in functioning relation with a machine into "which theweb is drawn incidentally'to 5 operation of'the machine,for example va re.- inforcing strip adapted to be appliedtobox blanks along their lines of scoring to strengthen the blanks where they are .ordinarily weakened by'scoring and to provide means on whichthe sections of the blanks may hinge when being formed into boxes or cartons, the present application being a, division from my co-pending application, Serial No. 108,556, filedMay 12, 1926,.Whereinthe 5 present invention was illustrated as applied to a lining machine. 1

Inoperating a machine .supplied with. a web, the web reel becomes exhausted and a new reel must be applied. The machine. must be stopped while the end of the web on the new reel is being attached tothe end ofqthe web in the machine, or otherwise introduced into. the machine; The principal object of my invention therefore, is to reduce to a minimum the retardation in operation of the ma chine due to the necessity for introducing a freshw eb T 4 Further objects of the invention are to facilitate the adjustment of strip-supporting 3o reels in relation to fixed positions toward which the strips are to ofreels. I a i It is further a particular object of them.-

The arm 10 comprisesapairof bars 11 having circulargenlargements112 interme diate their endsand spaced by ahubcollarl13' .having' flanges 14 secured to the en largements 12 byriyets 15,.the outer ends of i the bars being freeto provide. for ready in- Each of the arms is rotatable on an individual bushing 16 which iskeyed to, the shaft 9 by splines 17 which extend throughout. the length of the shaft,so thatgall of'the reel arms a a b .e l yederekh l t he shaf by the samepair ofsplines, thebushing have nd. flanges l8t in fl= m th s d o s arm and being locked against longitudinal the'set screws.

reinforcing s trip reels therebeangle to the horizontal, to hold the reinforc ing strip reel on its upper end in pro-per position for feeding a strip to the machine, the

arm being held in such set position by a plunger lock operable in a housing 20 secured ,to' the hub 13 ,by'screws or the like 21 and rality of sockets, an-dpreferably into either in a roll with a hole in the center thereof to of two diametrically opposite sockets 25 or 26inthebushing16. e-= a.

Fixed to the inner end of the base of the housing 20 isa cup 27, within which theinner end of the plunger may work, and surrounding the cup and the outer end of'the plunger and bearing against the baseof the cup and against a ring flange 28 on the plunger is an expansion spring 29, whereby the plunger is yieldably projected in the direction of the shaft'9; p r

The outer-endof thesh-ank 22 carries a handle 30 whereby the plunger may be withdrawn against the tension of its spring.

Withth'is arrangement the arms may be set on the shaft in position to properly support a reel of reinforcing strip and, when desired, the arm maybe released topivot on the shaft and relock in position after it has made a half turn, so that the opposite end of thearm is in the position for supportinga reel of reinforcing strip in functional -position. Y

The reinforcing strip is wound and stored permit the insertion of 'thereelj When the head 34, the'pin being adapted for projection through apertures 35 an'd 36 in the respective arm bars 11. The sleeve is of such length as to fit snugly between the bars, and one end as an extended flange 37 to which is secured a reel flange 38.

The other half of the reel comprises a sleeve 39 adapted to telescopeover the sleeve 32 ofthe other half of thefreel and of less length" than the sleeve, '32 so that oneend of 'thesleeve may bear against the inner, face of the flange 38, the opposite end havinga.

flange 40 carrying the reel flange 41, the reel flanges corresponding in diameter to properl-y contain the 'wound-stripof reinforcing ma- ,terial42.--

The reel is'lock'ed in place on the arm by a cotter pin 43 which is adapted for projecting through an aperture in the endof the pin opposite the head 34 and attached to the reel I arm by a chain or the like 44to prevent its loss or displacement whenthe reels are being changed. f

' Rotatably mounted in the standards 1 and revoluble within the pan 45 is; a ,moistening or gluing roller 46, and rotatably mounted in thestandards 1 above the roller-46 is a guide roller 47 for holding the strip of reinforcing material to the roller 46 and guiding it in the mined, the arms are adjusted on the shaft 9 to the proper spaced relation, the bushings of the several arms locked to the shaft by the set screws 19, the arms set by the plunger locks, and reels of strips mounted in the'upper ends of the arms, the strips being threaded between the rollers'46 and 47. v

The reels of the respective strips will be come exhausted, and new reels must be supplied. I anticipate emptying of the reels by applying similar reels to the lower ends of the arms 10 before the strips have been exhausted from the upper reels, it being apparent that the fresh reels may be applied to the lower ends of the arms without interfering with feed from the upper reels.

As the upper reel or reels become nearly exhausted, it is only necessary for me'to pull the plungers'which lock the arms to the shaft, turn the arms about until the fresh reels'are at the'top and the nearly empty reel or reels at the bottom, the reinforcing strip feeding into position from either top or bottom position of the reels, and then connect the ends of the fresh strips to theendsofthe strips exhausted from theprevious reels, soizthat feed of the strips may continue as before.

This interchanging of reels maybe efiected without material, ifany, interruption in the operation of a main machineand consequently little, if any, time is lost in the process of renewal of the reinforcing strips, the interchanges of full reels for empty ones being made from time to time as necessity demands, so that a full reel always on one end of each armready for use when'the active reel v latching the arms in selected means for mounting the arms slidably on the shaft, andlatching means including a member engaged with said mounting means to restrain the arms collectively against rotation and a plurality of members supported respectively by said arms and engageable with said mounting means for individually positions wit reference to the shaft. 7
